Implementing a robotic hepatopancreatobiliary program for new faculty: safety, feasibility and lessons learned.

Robotic surgery is increasingly utilized in hepatopancreatobiliary (HPB) surgery, but the learning curve is a substantial obstacle hindering implementation. Comprehensive robotic training can help to surmount this obstacle; however, despite the expansion of robotic training into residency and fellowship programs, limited data are available about how this translates into successful incorporation in faculty practice. All operations performed during the first three years of practice of a surgical oncologist at a tertiary care academic institution were retrospectively reviewed. The surgeon underwent comprehensive robotic training during residency and fellowship. 137 HPB operations were performed during the initial three years of practice. Over 80% were performed robotically each year across a spectrum of HPB procedures with a 6% conversion rate. Median operative time, a metric for operative proficiency and evaluation for a learning curve, was similar throughout the study period for each major operation and below several reported optimized operative time benchmarks. The major complications, defined as a Clavien-Dindo of 3 or more, were similar across the experience and comparable to published series. Comprehensive robotic training in residency and fellowship as well as a dedicated, well-trained operative team allows for early attainment of optimized outcomes in a new HPB robotic practice.

Implementing a Robotic Hepatopancreatobiliary Program for New Faculty: Safety, Feasibility and Lessons Learned.

Background: Robotic surgery is increasingly utilized in hepatopancreatobiliary (HPB) surgery, but the learning curve is a substantial obstacle hindering implementation. Comprehensive robotic training can help to surmount this obstacle; however, despite the expansion of robotic training into residency and fellowship programs, limited data is available about how this translates into successful incorporation in faculty practice. Methods: All operations performed during the first three years of practice of a complex general surgical oncology-trained surgical oncologist at a tertiary care academic institution were retrospectively reviewed. The surgeon underwent comprehensive robotic training during residency and fellowship. Results: 137 HPB operations were performed during the initial three years of practice. Over 80% were performed robotically each year across a spectrum of HPB procedures with a 6% conversion rate. Median operative time, the optimal metric for operative proficiency and evaluation for a learning curve, was similar throughout the study period for each major operation and below several reported optimized operative times. Major complications were similar across the experience and comparable to published series. Conclusion: Comprehensive robotic training in residency and fellowship as well as a dedicated, well-trained operative team allows for early attainment of optimized outcomes in a new HPB robotic practice.

Training and Evaluation of Residents to Ensure Competent Physician Metrics to Recognize Struggling Residents.

Assessing competency across domains of knowledge, skills, and behavior is critical to ensure that graduating orthopaedic residents possess the requisite skills and attributes to enter independent orthopaedic practice. Of the domains, knowledge is most easily assessed. In addition to the AAOS Orthopaedic In-Training Examination®, which provides a yearly gauge of residents' orthopaedic knowledge relative to their peers, there are several online platforms such as Orthobullets, the American Academy of Orthopaedic Surgeons ResStudy program, and the Journal of Bone and Joint Surgery Clinical Classroom that offer online learning resources and question banks. Clinical skills are best assessed through a combination of observation tools, including live or video assessments, 360° evaluations, and objective structured clinical examinations. Surgical skills can be evaluated in two domains: live surgical cases or simulations. The American Board of Orthopaedic Surgery is attempting to standardize live surgical evaluations through the use of the O-P tool. Although most available models feature only arthroscopic procedures, surgical simulators provide for opportunity to objectively evaluate resident performance. Behavior and professionalism has traditionally been the most challenging domain to assess. The American Board of Orthopaedic Surgery's Behavior Assessment Tool has demonstrated success in pilot testing and is being introduced as the standard for measuring behavior and professionalism in orthopaedic training. Although no single assessment tool can accurately gauge a resident's overall performance, a combination of readily available tools should be used to assess competence across domains.

Substantial Loss of Skeletal Muscle Mass Occurs After Femoral Fragility Fracture.

BACKGROUND: Femoral fragility fractures in older adults can result in devastating loss of physical function and independence. Skeletal muscle atrophy likely contributes to disability. The purpose of this study was to characterize the change in skeletal muscle mass, investigate the relationship with malnutrition and physical function, and identify risk factors for skeletal muscle loss. METHODS: Adults ≥65 years of age who were treated with operative fixation of an isolated femoral fragility fracture were enrolled in this multicenter, prospective observational study. Skeletal muscle mass was assessed within 72 hours of admission using multifrequency bioelectrical impedance analysis, which was repeated at 6 weeks, 3 months, and 6 months. Sarcopenia was defined by sex-specific cutoffs for the appendicular skeletal muscle mass index. The Mini Nutritional Assessment was used to measure nutritional status at the time of injury. Physical function was measured using the Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function domain. Linear mixed models were used to evaluate changes in skeletal muscle mass and PROMIS Physical Function scores over time and to evaluate factors associated with skeletal muscle mass changes. RESULTS: Ninety participants (74% female) with a mean age of 77.6 ± 9.0 years were enrolled. At the time of injury, 30 (33%) were sarcopenic and 44 (49%) were at risk for malnutrition or had malnutrition. Older age was associated with lower skeletal muscle mass (age of ≥75 versus <75 years: least squares mean [and standard error], -3.3 ± 1.6 kg; p = 0.042). From the time of injury to 6 weeks, participants lost an average of 2.4 kg (9%) of skeletal muscle mass (95% confidence interval [CI] = ‒3.0 to ‒1.8 kg; p < 0.001). This early loss did not recover by 6 months (1.8 kg persistent loss compared with baseline [95% CI = ‒2.5 to ‒1.1 kg]; p < 0.001). Participants with normal nutritional status lost more skeletal muscle mass from baseline to 6 weeks after injury compared with those with malnutrition (1.3 kg more loss [standard error, 0.6 kg]; p = 0.036). A 1-kg decrease in skeletal muscle mass was associated with an 8-point decrease in the PROMIS Physical Function (model parameter estimate, 0.12 [standard error, 0.04]; p = 0.002). CONCLUSIONS: We found that older adults with femoral fragility fractures lost substantial skeletal muscle mass and physical function. Participants with adequate baseline nutrition actually lost more muscle mass than those who were malnourished, indicating that future investigations of interventions to prevent muscle loss should focus on older adults regardless of nutritional status.

Comparisons of Procedures Performed in Training vs in Early Practice by Orthopaedic Trauma Surgeons.

INTRODUCTION: The Orthopaedic Trauma Association (OTA) has maintained an accreditation process of orthopaedic trauma fellowships with various requirements including an annually reviewed list of qualifying trauma cases in the form of American Medical Association Current Procedural Terminology (CPT) codes. The correlation between these established and monitored CPTs and the actual practices of orthopaedic trauma surgeons has not been studied. METHODS: American Board of Orthopaedic Surgery part II case logs (trauma subspecialty) (2012 to 2018) were compared with OTA fellowship case logs (2015 to 2019). Case logs from 447 surgeons and 166 trauma fellowship programs were compared. Four CPT code categories were defined: complex trauma (OTA required CPT codes, excluding Accreditation Council for Graduate Medical Education [ACGME] orthopaedic residency requirements), general trauma (ACGME residency required trauma codes), general orthopaedics (nontrauma ACGME residency requirements), and others (codes not included in residency or trauma fellowship requirements). RESULTS: OTA fellows performed a higher median percentage of complex trauma compared with American Board of Orthopaedic Surgery candidates (34% vs. 21%, P < 0.001): Both cohorts performed a similar percentage of general trauma (23%). OTA fellows performed more general orthopaedics (40% vs. 1%, P < 0.001). Several OTA required codes were performed infrequently (0 to 3 during board collection) by most surgeons, and several procedures are being performed that are not included in current CPT code requirements. DISCUSSION: Early-career traumatologists are performing orthopaedic trauma procedures they were trained on during residency and fellowship, with varying complexity. Trauma fellows perform a higher percentage of complex trauma compared with early-career trauma surgeons. Continued surveillance is necessary such that educational improvements can be made to maximize the quality of trauma fellowship education. LEVEL OF EVIDENCE: Level III, therapeutic study.

The Effect of Lumpectomy and Cavity Shave Margin Status on Recurrence and Survival in Breast-Conserving Surgery.

BACKGROUND/OBJECTIVE: Cavity shave margins (CSMs) decrease rate of positive margins and need for re-excision. Recurrence data following breast-conserving surgery (BCS) are not always available in large cancer registries. We sought to define our recurrence and survival data in BCS with routine excision of CSMs. METHODS: A single institution, 10-year retrospective review of breast cancer patients who underwent BCS with routine CSMs was conducted. Cavity shave margin technique was standard. Cox proportional hazard analyses and the Kaplan-Meier method were used to estimate recurrence and survival. RESULTS: Breast-conserving surgery with CSM was performed in 839 patients. Re-excision rate to achieve negative margins was 8.5%. Fifty-two patients (75%) underwent margin re-excision vs 18 patients (25%) underwent salvage mastectomy. Positive margin rate stratified by tumor histology was highest for invasive lobular carcinoma followed by mixed invasive ductal carcinoma (IDC) and ductal carcinoma in situ (DCIS), followed by pure DCIS and lowest for IDC. Length of follow-up was (4.7 ± 2.6, years). Overall recurrence rate (locoregional and systemic) was 4.3%: highest in patients with negative lumpectomy margin but positive CSM (L-S+ = 15%) followed by positive lumpectomy and CSMs (L+S+ = 14%), followed by patients with positive lumpectomy margin but negative CSMs (L+S- = 13%) and lowest for negative lumpectomy and CSM (L-S- = 5%), (P = .0008). There was no difference in 5-year breast cancer-specific survival between the 4 subgroups: 96% for L-S-, 86.7% L-S+, 94.7% L+S+ and 90% L+S- (P = .094). CONCLUSIONS: Recurrence following BCS with CSMs can be stratified based on both lumpectomy and cavity shave margin positivity. Routine excision of CSMs allows identification of these patient subsets.

Case report: Surgical resection of a retro-hepatic leiomyosarcoma involving atrial reconstruction, cardiopulmonary bypass, ex vivo tumor resection, and liver re-implantation.

Introduction: Leiomyosarcomas (LMS) involving the inferior vena cava (IVC) is a clinically rare entity, accounting for approximately 0.5% of all adult sarcomas. Case presentation: A 67-year-old male presented to the emergency department with mild back and lower abdominal pain. During the workup, a computed tomography scan without contrast showed an area of decreased attenuation within the liver adjacent to the intrahepatic IVC. Magnetic resonance imaging confirmed the involvement of the retro-hepatic IVC; biopsy confirmed the diagnosis of LMS. Given the location of the involvement of the retro-hepatic IVC, liver explantation was deemed necessary for adequate tumor resection. The superior extension of the tumor toward the heart necessitated Cardio-Pulmonary (CPB). The patient successfully underwent a complex surgical procedure involving liver explantation with ex vivo back-table resection of the retro-hepatic LMS, replacement of the retro-hepatic vena cava with a ringed Gore-Tex graft, liver re-implantation, and hepatic vein-atrial reconstruction under cardiopulmonary bypass. There were no intraoperative or post-op complications. Discussion: The role of vascular reconstruction of the IVC varies depending on the level and extent of the tumor, with options ranging from primary repair, ligation, or reconstruction dictated. Surgical resection with negative margins remains the treatment of choice due to the lack of efficacy of adjuvant therapies. Importantly, liver explantation offers a chance for complete surgical resection and reconstruction. Similarly, the complex nature of the tumor necessitated a pioneering approach involving direct hepato-atrial venous anastomosis. Conclusion: To the best of our knowledge, this is the first reported case in which the hepatic veins were anastomosed directly to the right atrium while also replacing the native vena cava with a separate graft.

American Board of Orthopaedic Surgery's Initiatives Toward Competency-Based Education.

The American Board of Orthopaedic Surgery (ABOS) is the national organization charged with defining education standards for graduate medical education in orthopaedic surgery. The purpose of this article is to describe initiatives taken by the ABOS to develop assessments of competency of residents to document their progress toward the independent practice of orthopaedic surgery and provide feedback for improved performance during training. These initiatives are called the ABOS Knowledge, Skills, and Behavior Program. Web-based assessment tools have been developed and validated to measure competence. These assessments guide resident progress through residency education and better define the competency level by the end of training. The background and rationale for these initiatives and how they serve as steps toward competency-based education in orthopaedic residency education in the United States will be reviewed with a vision of a hybrid of time and competency-based orthopaedic residency education that will remain 5 years in length, with residents assessed using standardized tools.

Conditionally Essential Amino Acid Supplementation Reduces Postoperative Complications and Muscle Wasting After Fracture Fixation: A Randomized Controlled Trial.

BACKGROUND: Postoperative complications and substantial loss of physical function are common after musculoskeletal trauma. We conducted a prospective randomized controlled trial to assess the impact of conditionally essential amino acid (CEAA) supplementation on complications and skeletal muscle mass in adults after operative fixation of acute fractures. METHODS: Adults who sustained pelvic and extremity fractures that were indicated for operative fixation at a level-I trauma center were enrolled. The subjects were stratified based on injury characteristics (open fractures and/or polytrauma, fragility fractures, isolated injuries) and randomized to standard nutrition (control group) or oral CEAA supplementation twice daily for 2 weeks. Body composition (fat-free mass [FFM]) was measured at baseline and at 6 and 12 weeks postoperatively. Complications were prospectively collected. An intention-to-treat analysis was performed. The relative risk (RR) of complications for the control group relative to the CEAA group was determined, and linear mixed-effects models were used to model the relationship between CEAA supplementation and changes in FFM. RESULTS: Four hundred subjects (control group: 200; CEAA group: 200) were enrolled. The CEAA group had significantly lower overall complications than the control group (30.5% vs. 43.8%; adjusted RR = 0.71; 95% confidence interval [CI] = 0.55 to 0.92; p = 0.008). The FFM decreased significantly at 6 weeks in the control subjects (-0.9 kg, p = 0.0205), whereas the FFM was maintained at 6 weeks in the CEAA subjects (-0.33 kg, p = 0.3606). This difference in FFM was not seen at subsequent time points. CONCLUSIONS: Our results indicate that CEAA supplementation has a protective effect against common complications and early skeletal muscle wasting after operative fixation of extremity and pelvic fractures. Given the potential benefits of this inexpensive, low-risk intervention, multicenter prospective studies in focused trauma populations are warranted. LEVEL OF EVIDENCE: Therapeutic Level I.

Non-functional pancreatic neuroendocrine tumours: ATRX/DAXX and alternative lengthening of telomeres (ALT) are prognostically independent from ARX/PDX1 expression and tumour size.

OBJECTIVE: Recent studies have found aristaless-related homeobox gene (ARX)/pancreatic and duodenal homeobox 1 (PDX1), alpha-thalassemia/mental retardation X-linked (ATRX)/death domain-associated protein (DAXX) and alternative lengthening of telomeres (ALT) to be promising prognostic biomarkers for non-functional pancreatic neuroendocrine tumours (NF-PanNETs). However, they have not been comprehensively evaluated, especially among small NF-PanNETs (≤2.0 cm). Moreover, their status in neuroendocrine tumours (NETs) from other sites remains unknown. DESIGN: An international cohort of 1322 NETs was evaluated by immunolabelling for ARX/PDX1 and ATRX/DAXX, and telomere-specific fluorescence in situ hybridisation for ALT. This cohort included 561 primary NF-PanNETs, 107 NF-PanNET metastases and 654 primary, non-pancreatic non-functional NETs and NET metastases. The results were correlated with numerous clinicopathological features including relapse-free survival (RFS). RESULTS: ATRX/DAXX loss and ALT were associated with several adverse prognostic findings and distant metastasis/recurrence (p<0.001). The 5-year RFS rates for patients with ATRX/DAXX-negative and ALT-positive NF-PanNETs were 40% and 42% as compared with 85% and 86% for wild-type NF-PanNETs (p<0.001 and p<0.001). Shorter 5-year RFS rates for ≤2.0 cm NF-PanNETs patients were also seen with ATRX/DAXX loss (65% vs 92%, p=0.003) and ALT (60% vs 93%, p<0.001). By multivariate analysis, ATRX/DAXX and ALT status were independent prognostic factors for RFS. Conversely, classifying NF-PanNETs by ARX/PDX1 expression did not independently correlate with RFS. Except for 4% of pulmonary carcinoids, ATRX/DAXX loss and ALT were only identified in primary (25% and 29%) and NF-PanNET metastases (62% and 71%). CONCLUSIONS: ATRX/DAXX and ALT should be considered in the prognostic evaluation of NF-PanNETs including ≤2.0 cm tumours, and are highly specific for pancreatic origin among NET metastases of unknown primary.

Contemporary Issues in the Acquisition of Orthopaedic Surgical Skills During Residency: Competency-Based Medical Education and Simulation.

➤: Orthopaedic education should produce surgeons who are competent to function independently and can obtain and maintain board certification. ➤: Contemporary orthopaedic training programs exist within a fixed 5-year time frame, which may not be a perfect match for each trainee. ➤: Most modern orthopaedic residencies have not yet fully adopted objective, proficiency-based, surgical skill training methods despite nearly 2 decades of evidence supporting the use of this methodology. ➤: Competency-based medical education backed by surgical simulation rooted in proficiency-based progression has the potential to address surgical skill acquisition challenges in orthopaedic surgery.

Do Orthopaedic In-Training Examination Scores Predict the Likelihood of Passing the American Board of Orthopaedic Surgery Part I Examination? An Update With 2014 to 2018 Data.

INTRODUCTION: Previous research shows a correlation in performance between the Orthopaedic In-Training Examination (OITE) and the American Board of Orthopaedic Surgery (ABOS) Certifying Examination Part I; however, these studies are not current, with the most recent data from 2009. The purpose of this study was to update the relationship between the OITE and ABOS Part I scores with the five most recent nationwide cohorts of Part I scores and their corresponding OITE scores. METHODS: The American Academy of Orthopaedic Surgeons provided the results for each resident taking the OITE from 2013 to 2017. The ABOS provided the results for each resident taking the Part I examination from 2014 to 2018. These two datasets were matched at the individual level and analyzed. RESULTS: Between 2014 and 2018, 3,502 first-time test-takers were present for the ABOS Part I Examination. A 96.6% pass rate was noted (3,383 of 3,502). A statistically significant correlation between the OITE score and ABOS Part I score was observed at all levels of training: postgraduate year (PGY) 1 r = 0.380, PGY2 r = 0.463, PGY3 r = 0.498, PGY4 r = 0.504, and PGY5 r = 0.504 (P < 0.001 for all correlations). CONCLUSION: The OITE scores continue to correlate with the ABOS scores and the pass rate for the ABOS with moderate strength correlation. However, although a correlation of the examinations exists when evaluated as a group, the predictive value of the OITE for passing the Part I examination for any specific individual is far from perfect. Individuals with PGY5 OITE percentile scores less than 10 pass the Part I examination, and individuals with PGY5 OITE percentile scores greater than 90 fail the Part I examination.

Lacking Advanced Degrees are not a Barrier to Entry into Academic Surgery Leadership.

BACKGROUND: Undergraduate and graduate medical education offerings continue to create opportunities for medical students to pursue MD+ degree education. These educational endeavors provide formal education in fields related to surgery, which gives trainees and surgeons diverse perspectives on surgical care. This study sought to assess current prevalence of additional advanced degrees among leaders in academic surgery to assess the relationship between dual degree attainment and holding various leadership positions within surgical departments. METHODS: The Association for Program Directors in Surgery database was used to identify academic surgical programs, which comprised our study population. Each department of surgery website in the APDS database was interrogated for departmental leaders and their reported academic degrees. RESULTS: Among 3223 identified surgeon leaders, 14.6% (470/3223) were found to possess MD+ degrees. Most common degrees possessed included MBA, MPH, and PhD. In comparing different types of surgeon leaders such as chairs, program directors, and division chiefs, no group was found to have a significantly higher prevalence of MD+ degrees than others. CONCLUSION: Prevalence of MD+ degrees among current academic surgery leaders is low, and the lack of an advanced degree should not be considered a barrier to entry into leadership positions. We hypothesize that these findings are likely to evolve as larger proportions of trainees obtain MD+ degrees during medical school and academic development time throughout residency.

Evaluation of clinical and imaging biomarkers for the prediction of new onset diabetes following pancreatic resection.

PURPOSE: To identify clinical and imaging biomarkers that can predict the new onset of diabetes mellitus (NODM) within 1 year of pancreatic resection. METHODS: A retrospective chart review was conducted of 426 non-diabetic patients who underwent a pancreaticoduodenectomy or distal pancreatectomy at the University of Pittsburgh Medical Center between 2006 and 2016. Clinical characteristics and the patient's diabetic status at 1-year post resection were collected from the EMR. Imaging biomarkers included hepatic and pancreatic fat replacement, pancreatic calcifications, pancreatic duct diameter, pancreatic volume and body composition. Univariate and multivariable analyses were performed to demonstrate any predictive biomarkers of diabetes occurrence within 1 year of pancreatic resection. RESULTS: 135/426 (31.7%) patients developed NODM. The only significant clinical predictor was older age (OR 1.02, 95% CI 1.002-1.039, p = 0.032). Imaging characteristics found to be significant included hepatic steatosis (OR 1.777, 95% CI 1.094-2.886, p = 0.02), larger reduction in pancreas volume (OR 0.989, 95% CI 0.979-0.999, p = 0.027), and greater preoperative visceral fat (OR 1.004, 95% CI 1.001-1.006, p = 0.001). CONCLUSION: Age, presence of hepatic steatosis, change in pancreatic volume, and preoperative visceral fat are independent predictive biomarkers for NODM following pancreatic resection.

Surgical Skill Can be Objectively Measured From Fluoroscopic Images Using a Novel Image-based Decision Error Analysis (IDEA) Score.

BACKGROUND: To advance orthopaedic surgical skills training and assessment, more rigorous and objective performance measures are needed. In hip fracture repair, the tip-apex distance is a commonly used summative performance metric with clear clinical relevance, but it does not capture the skill exercised during the process of achieving the final implant position. This study introduces and evaluates a novel Image-based Decision Error Analysis (IDEA) score that better captures performance during fluoroscopically-assisted wire navigation. QUESTIONS/PURPOSES: (1) Can wire navigation skill be objectively measured from a sequence of fluoroscopic images? (2) Are skill behaviors observed in a simulated environment also exhibited in the operating room? Additionally, we sought to define an objective skill metric that demonstrates improvement associated with accumulated surgical experience. METHODS: Performance was evaluated both on a hip fracture wire navigation simulator and in the operating room during actual fracture surgery. After examining fluoroscopic image sequences from 176 consecutive simulator trials (performed by 58 first-year orthopaedic residents) and 21 consecutive surgical procedures (performed by 19 different orthopaedic residents and one attending orthopaedic surgeon), three main categories of erroneous skill behavior were identified: off-target wire adjustments, out-of-plane wire adjustments, and off-target drilling. Skill behaviors were measured by comparing wire adjustments made between consecutive images against the goal of targeting the apex of the femoral head as part of our new IDEA scoring methodology. Decision error metrics (frequency, magnitude) were correlated with other measures (image count and tip-apex distance) to characterize factors related to surgical performance on both the simulator and in the operating room. An IDEA composite score integrating decision errors (off-target wire adjustments, out-of-plane wire adjustments, and off-target drilling) and the final tip-apex distance to produce a single metric of overall performance was created and compared with the number of hip wire navigation cases previously completed (such as surgeon experience levels). RESULTS: The IDEA methodology objectively analyzed 37,000 images from the simulator and 688 images from the operating room. The number of decision errors (7 ± 5 in the operating room and 4 ± 3 on the simulator) correlated with fluoroscopic image count (33 ± 14 in the operating room and 20 ± 11 on the simulator) in both the simulator and operating room environments (R2 = 0.76; p < 0.001 and R2 = 0.71; p < 0.001, respectively). Decision error counts did not correlate with the tip-apex distance (16 ± 4 mm in the operating room and 12 ± 5 mm on the simulator) for either the simulator or the operating room (R2 = 0.08; p = 0.15 and R2 = 0.03; p = 0.47, respectively), indicating that the tip-apex distance is independent of decision errors. The IDEA composite score correlated with surgical experience (R2 = 0.66; p < 0.001). CONCLUSION: The fluoroscopic images obtained in the course of placing a guide wire contain a rich amount of information related to surgical skill. This points the way to an objective measure of skill that also has potential as an educational tool for residents. Future studies should expand this analysis to the wide variety of procedures that rely on fluoroscopic images. CLINICAL RELEVANCE: This study has shown how resident skill development can be objectively assessed from fluoroscopic image sequences. The IDEA scoring provides a basis for evaluating the competence of a resident. The score can be used to assess skill at key timepoints throughout residency, such as when rotating onto/off of a new surgical service and before performing certain procedures in the operating room, or as a tool for debriefing/providing feedback after a procedure is completed.

Formal robotic training diminishes the learning curve for robotic pancreatoduodenectomy: Implications for new programs in complex robotic surgery.

INTRODUCTION: The learning curve associated with robotic pancreatoduodenectomy (RPD) is a hurdle for new programs to achieve optimal results. Since early analysis, robotic training has recently expanded, and the RPD approach has been refined. The purpose of this study is to examine RPD outcomes for surgeons who implemented a new program after receiving formal RPD training to determine if such training reduces the learning curve. METHODS: Outcomes for consecutive patients undergoing RPD at a single tertiary institution were compared to optimal RPD benchmarks from a previously reported learning curve analysis. Two surgical oncologists with formal RPD training performed all operations with one surgeon as bedside assistant and the other at the console. RESULTS: Forty consecutive RPD operations were evaluated. Mean operative time was 354 ± 54 min, and blood loss was 300 ml. Length of stay was 7 days. Three patients (7.5%) underwent conversion to open. Pancreatic fistula affected five patients (12.5%). Operative time was stable over the study and lower than the reported benchmark. These RPD operative outcomes were similar to reported surgeon outcomes after the learning curve. CONCLUSION: This study suggests formal robotic training facilitates safe and efficient adoption of RPD for new programs, reducing or eliminating the learning curve.
